PAUL SINNHOLD, OF ST. LOUIS, MISSOURI.

IMPROVEMENT IN COMB INED SEED-PLANTER AND CULTIVATOR.

Specification forming part of Letters Patent No. 49,661, dated August29, 1865.

To all whom it may concern:

Be it known that I, PAUL SINNHOLD, of the city and county of St. Louis,and State of Missouri,have invented a new and useful Improvement inCombined Seed-Planters. and Cult-ivators; and I do hereby declare thatthe following is a full and clear description thereof, reference beingbad to the accompanying drawings, and to theletters of reference markedthereon, and made to form apart of this specification.

The obj ect of this invention is to produce a new farming implement thatmay be employed for seed-plantin g, cultivating, plowing, or distributing fertilizers, and which maybe worked with less positive power, greaterregularity, and ease in management (while in motion) by the operator, ineffecting like results, than any implement now in use for similarpurposes 5 and the nature or subject-matter of the improvement relatesto the use of a single wheel arranged to support the machine at itscenter of gravity; to adjustable central joints or bearings of the beamsor side frames of the machine, in combination with the supportingaxleand also to the arrangement of the draft attachments.

In reference to the accompanying drawings, Figure 1 represents a sideelevation, and Fig. 2 a top view or plan, of my improvement; and Fig. 3is a horizontal sectional view,'representing the formation of theadjustable joints of the beams or side frames.

A represents the supporting-wheel, so arranged that its bearing-pointupon the ground will be the center of gravity of the entire machine,assustained by said wheel,which is provided with an axle, B, adapted tocarry the beams C U. The axle B will be cast or provided with twoball-rings, one at each end, as (I, (seen in Fig. 3,) which are adaptedto fit and rotate in spherical sockets prepared for them in the beams OO, the poles of said spherical sockets being formed horizontally oval,(see Figs. 1 and 3,) by means of which the ends of said beams areallowed free lateral and vertical motion, and at the same time thecultivatin g,plowing, or seeding devices carried by said beams will bemaintained always in their proper upright positions. These said beams O(l are entirely independent of each other in their operation, and bymeans of the adj ustable joints above described are renderedindividually adaptable to the surface of the ground over which themachine may be operated, and their lateral management placed under thecontrol of the operator through the medium of the handles ff. Directlyunder the axis or center of motion each of the beams G G will beprovided with a screw-bolt. (see g, Fig. 1,) earryiug an adjustablering-nut, g, to which the draft-cords, 7th, chains, or rods will beattached, and these devices h h will be made to pass through theadjustable eyebolts t' t of the beams C G, by means of which arrangementsaid beams may be regulated in such manner that the cultivating devicesat their ends may operate upon the same plane, or so that the saiddevices, either at the rear or front ends of the beams, as the case maybe, according to the nature of the work, may be made to run deeper inthe ground than at the opposite ends of the beams, and also withreference to the elevation of the front ends of the devices h h, asattached to different draft-animals.

The cultivator teeth, plows, or devices used in opening the ground forseed may be carried by suitable frames, as k k, Fig. 1, at each of theends of the beams. These frames are rigidly secured to standards Z l,and these standards are made to pass through clamps m m, where they maybe adjusted as desired and secured by means of set-screws n n. Saidclamps m m may be adjustable laterally by means of keys or wedges, andthereby secured in a proper manner upon the beams. (See Fig. 2.)

p 19 represent seed-hoppers, that may be secured upon the standards I lin such manner as to be adjustable with reference thereto and removabletherefrom by means of set-screws Ordinary seed-spouts, arranged in theusual manner, may be employed to conduct theseed from the hoppers to theground, and the seed in the hoppers may be suitably agitated and fed tothe spouts by means of eccentric-rods r r of shaft 8. Said shafts willbe furnished with suitable bearings in standards of the beams G 0,directly over the axis of motion, andthese bearings will be made withadjustable joints, so that said shaft 8 may not interfere with the freeindividual operation of the beams, as before described. Said shaft maybe actuated by means of pulleys and belts from the axle B.

t represents a cleaner, or a device for removing obstructions before thepassage of the] wheel. Its point will befashionedlike a shovelplow, andit will be carried bymeans of its two arms, which have universalbearings or joints in the beams O O, as seen at v,Fig. 1. Leading fromthe point of this devicet forward is a rod, t,which passes with ascrew-thread through a cross-bar, 10, through the ends of which thedraft devices h h are made to pass. The said bar 20 is made adjustableon the rod t bymeans of the nuts 93 w, by means of which the position ofthe point of the cleaner or device It may be regulated as desired.

Whenused asa plow the beams O 0 will be braced at their ends with crossbars or rods, which render said beams rigid and harmonious in theirlateral action. The plows will be attached one to the forward end of onebeam and one to the rear end of the other beam, the center of gravity ofthe entire machine being still maintained at the center of motion, sothat the two plows may be as readily handled as one.

Having thus described my improvement,

what I claim, and desire to secure by Letters Patent, is-

1. The combination and arrangement of the wheel A with the handles ff,and with the draft-cords h h, the same forming two triangles whoseapexes are in the axis of A, and by the application ofpower at theirbasesff and hh acting to preserve the correct equilibrium of the entiremachine.

2. Theadjustable central joints or bearings of the beams G G, incombinationwith a supporting-axle, B, or its equivalent, all beingconstructed and arranged to operate substantial] y as and for thepurposes set forth.

3. The arrangementand combination of the draft attachments comprisingthe adjustable ring-nuts 9, adjustable eyebolts i i, or theirequivalents, and the cords, rods, or chains hh, substantially as and forthe purposes herein set forth and specified.

In testimony of which invention I have hereunto set my hand andseal,this 5th day of Sep tember, 1864.
